Markdown: Link key converted to lower-case

See original GitHub issue

Prettier 1.19.1 Playground link

--parser markdown

Input:

- see[Link to Foo][master-LinkToFoo]

[master-LinkToFoo]: http://foo.com

Output:

- see[Link to Foo][master-linktofoo]

[master-linktofoo]: http://foo.com

Expected behavior:

- see[Link to Foo][master-LinkToFoo]

[master-LinkToFoo]: http://foo.com

Making the key lower case reduces the readability of Camel or Pascal cased keys. This seems to have changed recently? Was the change intentional? Can you share the justification?

Just seconding that this cuts against readability and correctness. Often link reference definitions read as a glossary, e.g.:

[darktable]: https://www.darktable.org/
[js;dr]: https://indieweb.org/js;dr
[LinuxFest Northwest]: https://www.linuxfestnorthwest.org/
[OpenStreetMap]: https://www.openstreetmap.org/about
[SeaGL]: https://seagl.org/
[uBlock Origin]: https://github.com/gorhill/uBlock

and it would be a spelling error to change a label’s capitalization.

I’ve just come across this issue with CHANGELOG.md files following the Keep a Changelog format. For example:

Input:

## [Unreleased]
…
[Unreleased]: https://github.com/username/project/compare/v1.0.0...HEAD

Output:

## [Unreleased]
…
[unreleased]: https://github.com/username/project/compare/v1.0.0...HEAD

Expected behaviour:

No change from input.
